I'm using Jqxgrid of jqwidgets.

I have taken a dropdown list in a grid.

I want to show dropdown list in editable mode by default on page load.

Below is the code.

{
                text: 'Position of meter in Rack', datafield: 'MeterPositionInRack', width: 180, columntype: 'dropdownlist', editable: true,
                createeditor: function (row, column, editor) {
                    var list = ['1', '2', '3' ,'4'];
                    editor.jqxDropDownList({ autoDropDownHeight: true, source: list, selectedIndex: 0 });

                    editor.jqxDropDownList.bind('select', function (event) {
                        var args = event.args;
                        var item = $('#jqxdropdownlist').jqxDropDownList('getItem', args.index);
                        alert('Selected: ' + item.label);
                    });
                }
                , initeditor: function (row, cellvalue, editor) {
                    var list1 = ['1', '2', '3', '4'];
                    console.log("initeditor: " + list1);
                    editor.jqxDropDownList({ autoDropDownHeight: true, source: list1, selectedIndex: 0 });
                }
            }

Please help me.

Jqxgrid has ready properties to do anything after the grid is initialized and the binding is complete, so you can trigger begin update method:

$("#jqxgrid").jqxGrid({
 ...
 ready: function () {
          $("#jqxgrid").jqxGrid('beginrowedit', 0);
      },
 ...
 });
